My return was rejected because of carryover losses but I didn't have any

Can you provide more details, reject code and explanation?

I recommend deleting this carryover worksheet since it is not applicable to  you.

Here's the general procedure for viewing the forms list and deleting unwanted forms, schedules, and worksheets in TurboTax Online:

1. Open or continue your return in TurboTax.
2. In the left menu, select Tax Tools and then Tools.
3. In the pop-up window Tool Center, choose Delete a form.
4. Select Delete next to the carryover worksheet in the list and follow the instructions.

If this is related to rental property that you own, I seriously doubt (though it is possible) that you did not have carry over losses. What is the exact reject code or message you get? Not taking your carry overs will cost you big time in the future when you sell or otherwise dispose of the property. So instead of just deleting it, lets get it right. Last thing you want is to lose what may be serveral years of carry overs. That *WILL* hurt in the future.
